Title: Measuring device of surface potential of photosensitive body in copying machine
Inventor: MAEHARA SHIGEJI
IPC: G03G15/00
Filed: 1983-10-14
Abstract: PURPOSE:To stabilize always detection of the surface potential of a photosensitive body by providing a means which shields a potential detecting electrode facing the photosensitive body and measuring an induced potential generated in the potential detecting electrode in the state where shielding is released. CONSTITUTION:Before the start of measurement, a potential detecting electrode 7 is shielded by a hollow cylinder 8, and a relay 13 is closed. At the measurement start time, the hollow cylinder 8 is rotated, and the relay 13 is opened just before an aperture part 10 of this cylinder 10 faces a photosensitive drum 5. The induced potential generated in the potential detecting electrode 7 is measured to detect the surface potential of the photosensitive drum 5. After one measurement is terminated in this manner, the hollow cylinder 8 is returned to the state before the start of measurement, and the relay 13 is closed, and they are held until measurement is started again. Hereafter, the similar operation is repeated. Thus, the time of one measurement is shortened to several seconds or shorter, and the attenuation quantity of voltage due to attenuation characteristic is held down to a small value, and the surface potential of the photosensitive body is always measured stably.

Title: Apparatus for measuring moisture content of printing ink
Inventor: TEJIMA AKITOMO
IPC: G01N27/60
Filed: 1994-08-17
Abstract: PURPOSE:To improve a reliability of an apparatus by making the apparatus possible to automatically measure/control a moisture content of a printing ink of an Indian ink color and to be easily set in any printing machine. CONSTITUTION:A corona charger 25 is arranged in the vicinity of the surface of a conductor roller 21 among a group of ink rollers of a printing machine, and surface potential-measuring devices 27, 28 are disposed on the downstream side from the corona charger 25. A moisture content is obtained by measuring a charge potential. Although the charge potential is proportional to a film thickness of a printing ink, the film thickness can be measured by the photoacoustic technique even in the case of an Indian color ink. Therefore, the moisture content of the Indian color ink can be identified by measuring the charge potential and the film thickness after obtaining a calibration graph of relation between the charge potential and the moisture content per 1mum of a printing ink of a known moisture.

Abstract: PURPOSE:To reduce the required analysis time by enabling the correction of disturbing X-ray with a single X-ray spectrometer without scanning wavelength. CONSTITUTION:A wave height analyzer 4 is set at LU1 for the upper limit and LL1 for the lower limit in the window of selecting wave height and a wave height analyzer 4' at LU2 for the upper limit an LL2 for the lower limit in the window. Here, the values LU1 and LL1 are set both before and after the peak  A. The peak B is in the wave length distribution of disturbing X-rays and the values LU2 and LL2 are set at a part not overlapping the pulse of the peak A. The pulse section in the X-rays of the wavelength to be measured corresponds to pulses passing the windows LU1 and LL1 of the wave height analyzer 4 excluding the shade part. The count output IB of a counter 5' corresponding to the shade part purely gives the height of the peak B, where K is constant in the relationship of iB=K.IB. When the count of a counter 5 is put at iA, this is the sum of counts IA and iB of pulses in the X-ray of the wavelength to be measured and the count IA of the pulses is given by IA=iA-K.IB. From the counting of pulses within a fixed time, the intensity of the X-ray of the intended wavelength can be measured.

IPC: B23K26/00
Filed: 1994-07-26
Abstract: PURPOSE:To provide the welding of high quality at low cost by achieving the roll pressing of a sheet part in the prescribed range from the boundary of the weld zone parallel to the weld zone in a butt welded joint to prevent the deformation in the longitudinal direction of the member to be welded. CONSTITUTION:In the butt welding of aluminum sheet and aluminum alloy sheet 1, the aluminum alloy sheet 1 in the range 3 of 30mm from the boundary of the weld zone 2 is pressed by rolls 4, 5 parallel to the weld zone. The width of the pressing is preferably and normally 5-30mm, and the degree of the pressing is preferably and normally the rolling reduction of about 1% of the sheet thickness. The trend of shrinkage in the direction parallel to the weld zone 2 is weakened by the pressing of the rolls 4, 5 in the vicinity of the weld zone 2, and the residual compressive stress is also reduced to allow the correction of the buckled deformation. This constitution prevents the deformation in the longitudinal direction of the member to be welded of the aluminum alloy sheet 1 to obtain the welding of high quality.

Filed: 1986-08-19
Abstract: PURPOSE:To prevent the robbery of a vehicle by automatically setting covering members for such openings as side windows or the like at their stand-by positions when crewman's absence and closed vehicle doors are detected, and converting the vehicle into a damage preventing mode when the vehicle turns into operating condition without the normal release of door locking. CONSTITUTION:Crew detecting circuits PD1-PD4 to detect crewman's presence or absence on a vehicle, door latch switches LA1-LA4 to detect the opening or closing of vehicle doors, and door key switches KS1, KS2 to detect that a lock releasing means has acted on a door locking mechanism are provided. When the crewman's absence and closed vehicle doors are detected, a driving mechanism sets covering members for such openings as side windows or a sunroof at their stand- by positions. After then, when the crewman's presence of any opened vehicle door is detected before it is detected that said releasing means has functioned, said vehicle is set in a damage preventing mode,and a drivers seat and a steering wheel are therefore moved to reduce a space between them so as to turn the vehicle into an uncontrollable condition.

Title: Horizontal detector
Inventor: IMAI SHUNZO
IPC: G03F7/20
Filed: 1984-09-18
Abstract: PURPOSE:To automatically dispose an exposure unit horizontally by detecting the displacement of the structure of superposed members from the neutral position corresponding to the vertical axis of the structure, and horizontally returning it. CONSTITUTION:Assume that the horizontality of a horizontal detector is displaced in more than allowable amount so that the supporting height of an air damper 1a is, for example, increased in higher. If superposed members 23 moves by their own weight in a horizontal detector 19 to be disposed at the position designated by broken lines 23', a photoswitch 25c becomes OFF. Since at this time photoswitches 25a, 25b are respectively connected with solenoid valves, the solenoid valves of the damper 1c is opened by a signal from a switch 25c which became OFF, air is supplied into the damper 1c to pressurize the damper 1c, thereby rising its position. Thus, when the detector returns to the horizontal position, a yarn member 24 becomes perpendicular to the detector, the superposed member 33 becomes neutral with respect to the vertical axis of the structure to turn ON the switch 25c. As a result, the damper 1c is closed so that the printing exposure unit is returned to the horizontal position.

IPC: B29C65/06
Filed: 1998-07-09
Abstract: PROBLEM TO BE SOLVED: To check the development of burrs at welding and improve a joining strength by a method wherein the tip of a joining piece, the width of which is narrower, is provided in advance so as to have a sectional form with a specified number of projecting parts. SOLUTION: When a first member 1 made of synthetic resin and a second member are welded together, the tip of the joining piece 10, the width of which is narrower, is provided in advance so as to have a sectional form with two projecting parts 12. Then, the joining pieces 10 and 20 are pressingly abutted against each other. Under the state just mentioned above, vibration is applied to the first member 1 and the second member 2 so as to develop a frictional heat between the joining pieces 10 and 20. Thus, first of all, the projecting part 12 of the joining piece 10 and the abutting portion of the joining piece 20 start to melt.  In this case, by providing the projecting parts 12 in the joining piece 10, a recessed part 19 is formed, resulting in entering the melted resin developing at the early stage of a vibratory welding within the recessed part 19 and checking the development of burrs. In addition, the joining boundary part 50 of the welding part becomes wavy, resulting in increasing an anchoring effect and a joining area and consequently improving a joining strength.

Abstract: PURPOSE:To reduce the size of an element having super self-alignment transistor structure by forming each side of an emitter region at approximately equal distances from a boundary between an element region and an isolation region in the periphery of the element region. CONSTITUTION:A field oxide film 11 for isolation, an element region, is shaped to the main surface of a semiconductor substrate 1. A P<+> type external base region 13a is formed while being self-aligned with an N<-> type epitaxial layer 4 shaped in the element region. a P-type intrinsic base region 13b, which is self-aligned and continues to the region 13a, and an N-type emitter region 19 are formed. The region 19 is shaped separated only by approximately equal distances from several side of a boundary between the region 13a and the film 11 at that time. Consequently, only one mask may be used for forming the element region, the region 13a and the region 19. Accordingly, the allowance of mask alignment need not be prepared, thus reducing the size of an element for a transistor only by a section corresponding to the unnecessity of the allow ance of mask alignment, then accelerating the speed of operation of the transis tor.

Title: Etching method for thin film
Inventor: SOMEYA TOMOYUKI
IPC: H01L21/302
Filed: 1986-08-22
Abstract: PURPOSE:To enable a fine pattern to be formed with high precision, by using a silicon oxide film or a silicon nitride film as a mask for patterning, and by performing reactive ion etching in plasma of a mixed gas consisting of carbon tetrachloride and oxygen. CONSTITUTION:Inorganic films made of SiO2, Si3N4, or the like is used as a mask, and reactive ion etching of a material to be etched is performed by the use of a mixed gas consisting of CCl4 and O2. Because a SiO2 film 2 serving as a mask is fully small in a speed of etching by plasma of CCl4 +O2, a polycrystal silicon film 3 after processing has no deterioration in a size and has no shifting in a dimension. Because of no generation of C, films sticking on side walls can be decreased. Thereby, a gate electrode formed of the polycrystal silicon film 3 or the like can be processed with high dimensional precision, and its selection ratio to SiO2 or the like of a base film can be maintained high, and the films as foreign matters sticking on the side walls can be prevented from being generated.
